Create a struct name Set that contains a Vector of chars and overload the minus operator so that when 2 structs subtract it removes the chars of 2nd from 1st one.

Create a struct named ComplexNumber that has 2 variables re & im and overload minus and plus operator to add and subtract complex number.

Overload the ! operator to conjugate the complex number !ComplexNumber and == and != for comparison.

Create a struct named Class that contains the class size, section and grade. Overload the >, <, >=, <=, == operators to compare class sizes of various Classes.

Rust does not allow addition of integer and float. Overload + so that this is possible.

Implement custom Drop for a struct Hero that contains a field name of type string. The drop should print "Oh no !!! Our hero {name} is defeated". Run the program with just declaring a variable of type Hero.

Create the struct named World that contains the previous named struct Hero, define drop for it so that it prints "The world ends here !!!". Observe the order in which World and Hero contained by it are dropped.

Create a struct named Table that has a generic field legs_info of type T. Create a function (not a method) named show that accepts function parameters &Table<Display> and displays legs_info. Create 2 variables one that contains T of type String: "Work in progress..." and usize: 4.
hint: use ?Sized.

Implement From trait for struct ComplexNumber given a tuple of type (isize, isize). Form it using from and into respectively.

Create a function that accepts either ComplexNumber or (isize, isize) to return the mod of ComplexNumber.
